What is budding in plant propagation?

• Joining two plants to grow separately

• Joining two plants to grow as one

• A method of seed germination

• A process of root pruning

What is the scion in budding?

• The root system of the plant

• A piece of stem with a dormant bud

• A fully developed rootstock

• The soil layer for propagation

What is the primary function of the rootstock in budding?

• Form the upper portion of the plant

• Develop into the root system

• Produce flowers directly

• Absorb atmospheric nitrogen

Which type of buds is preferred for scion selection?

• Vegetative buds

• Flowering buds

• Dormant buds

• Seed buds

Why are leaves removed from scions during transportation?

• To make the scion lighter

• To reduce water loss

• To leave the petiole intact and prevent moisture loss

• To promote bud sprouting

What is the ideal age for rootstock in budding?

• 1-2 months

• 3-4 years

• 6 months to 1 year

• 2-3 years

What must align for successful budding?

• Leaf buds

• Vascular cambiums of scion and rootstock

• Root hairs

• Axillary nodes

What is the purpose of the callus bridge in budding?

• o prevent water loss

• To form seeds

• To connect scion and rootstock tissues

• To absorb nutrients

Which tissue forms first during bud union healing?

• Phloem

• Cambium

• Xylem

• Epidermis

Which method is widely used for propagating fruit trees?

• Patch budding

• Flute budding

• Chip budding

• Ring budding
